Measurement setup 

The IVC-3D maximum field-of-view (FOV) is determined by the size of the housing, the lens 

system and the laser fan angle. The FOV is placed at a certain distance from the device, 
the stand-off, and is a trapezoid shaped area in the laser plane. The maximum height and 

the maximum width of an inspected object define a rectangle which must be entirely inside 
the trapezoid total FOV.  
 
 

 

Figure 5.1 – Explanation of  IVC-3D FOV. 

 
The measurement speed is dependent on required resolution in the length (moving)  

direction. The device grabs profiles at a rate determined by the settings in the software 
tool 

Grab setup

. The possible profile speed in a specific application is dependent on the 

chosen measurement accuracy and chosen laser strength.
